Church attendance, not mere membership, moderates the religion-prejudice link

Evidence

Given this powerful conclusion, researchers have tried to find a subset of church members who are as unprejudiced as those who belong to no church. Gorsuch and Aleshire (1974) pointed out, for example, that many people say they belong to a church but do not attend it. If these people are highly prejudiced, they will give religion a bad name in studies that just examine membership. — Bob Altemeyer, The Authoritarian Specter, 1978
